DataSift :The Story So Far and Focus for the Future

DataSift, the company with an impressive BigData architecture, has raised another $7.2mil to accelerate the growth:

Maybe our biggest surprise to me is the breadth of use-cases that we’re seeing companies use our Social Data platform for. Social Media Monitoring and “Breaking News” are obvious applications that companies build.  But we’re seeing everything from Business Intelligence, Stock-Trading models, Public-health applications and social-TV guides being built with DataSift.  A big part of Nick’s vision has always been to democratize the social data market – opening it to both small and large companies. We are starting to see this play-out.

I don’t think anyone would contradict me when saying that these are just the tip of the iceberg when speaking about Big Data.

DataSift Using MySQL, HBase, Memcached to Deal With Twitter Firehose

A new great article from Todd Hoff dissecting the DataSift architecture:

In terms of data store, DataSift architecture includes:

  • MySQL (Percona server) on SSD drives
  • HBase cluster (currently, ~30 hadoop nodes, 400TB of storage)
  • Memcached (cache)
  • Redis (still used for some internal queues, but probably going to be dismissed soon)

Leave whatever you were doing and go read it now.

DataSift PubSub: From Redis to Kafka and 0mq

DataSift moves from Redis PubSub to Kafka and 0mq :

Kafka is still a young project, but it’s maturing fast, and we’re confident enough to use it in production (as a matter of fact, we’ve been using it for months now) in front of our HBase cluster and to collect monitoring events sent from all our internal services. We chose Kafka especially for its persistent storage (which is essentially a partitioned binary log), but we plan to do some analytics via its support for Hadoop soon. And its distributed nature (coordination beetween consumers and brokers is done via Zookeeper) makes it very appealing too.
